Number 3..................
Since we know that The angle of depression from the airplane to the airport is 40°, and its altitude is 10000 feet, we can create a right triangle using the horizontal of the plane, the angle of depression, and the altitude as one of the legs of our right triangle. the horizontal (ground distance) from the airport to the airplane's<span> will be the same as the adjacent leg of our depression angle. To find the adjacent leg we'll need a trig function that relates our leg with the depression angle and the opposite leg. That trig function is tangent. So lets set up an equation and solve it to find our distance:
</span>
<span>
We can conclude that </span><span>the horizontal (ground distance) from the airport to the airplane's position is
11,917.54 feet.</span>
Answer:
Step-by-step explanation:
Since the height of each bounce is 3/4 of its last peak height we can use a geometric sequence to find the bounce height for any number of bounces.
h=12(3/4)^b
h(5)=12(3/4)^5
h(5)=2.85m
The power of the man is 233.33 W
We'll begin by calculating the energy used by the man. This can be obtained as follow:
Mass (m) = 35 Kg
Height (h) = 0.50 m
Acceleration due to gravity (g) = 10 m/s²
<h3>Energy (E) =? </h3>
<h3>E = mgh </h3>
E = 35 × 10 × 0.5
<h3>E = 175 J</h3>
Thus the man used 175 J of energy.
Finally, we shall determine the power. This can be obtained as follow:
Energy (E) = 175 J
Time (t) = 0.75 s
<h3>Power (P) =? </h3>
<h3>Power = Energy / time </h3>
Power = 175 / 0.75
<h3>Power = 233.33 W </h3>
Therefore, the power of the man is 233.33 W
